The Delhi High Court on Tuesday asked the poll panel to file a detailed affidavit on the eight AAP MLAs plea challenging their disqualification for holding office of profit.
A division bench of Justice Sanjiv Khanna and Justice Chander Shekhar sought the response from the Election Commission and listed the matter for a February 7 hearing.
The court also extended its interim order which restrained the EC from announcing by-polls for the vacated seats.
The disqualified lawmakers had moved the High Court last week.
Their counsel has argued that the notification is a "gross violation of natural justice because the Election Commission decided the matter in undue haste and without affording and giving any opportunity of fair hearing to the petitioners".
Following the poll panel's recommendation to President Ram Nath Kovind, the Law and Justice Ministry issued a notification that the President had "okayed" the disqualification of 20 Delhi AAP MLAs.
The disqualified MLAs are Alka Lamba, Adarsh Shastri, Sanjeev Jha, Rajesh Gupta, Kailash Gahlot, Vijendra Garg, Praveen Kumar, Sharad Kumar, Madan Lal Khufiya, Shiv Charan Goyal, Sarita Singh, Naresh Yadav, Rajesh Rishi, Anil Kumar, Som Dutt, Avtar Singh, Sukhvir Singh Dala, Manoj Kumar, Nitin Tyagi and Jarnail Singh.
The AAP MLAs were disqualified over charges of holding â€˜office of profitâ€™. The action taken by the former Chief Election Commissioner AK Joti just before relieving from the post came under public scrutiny, who questioned his credibility.
While both the BJP and Congress upheld the decision, AAP cried foul of vendetta by the Prime Minister.
AAP also launched a full-scale attack on the former CEC and said that he was â€˜repaying the debtâ€™ to Prime Minister Narendra Modi before his retirement.
Jotiâ€™s image remains tarnished as was also earlier accused of showing bias to the BJP by not announcing the Gujarat poll dates on time.
